Is It Just Aging, or Depression? Signs Older Adults and Their Families Often Miss

By Erica Coleman · October 21, 2026

Sleeping badly, losing interest in old hobbies, feeling tired all the time. It is easy to file those changes under getting older. The National Institute on Aging says that would be a mistake. Depression is common among older adults, but it is not a normal part of aging, and most older people feel satisfied with their lives even when they have more health problems than younger people do.

Part of what makes depression hard to spot later in life is that it often doesn’t look like sadness. NIA says some older adults feel emotional numbness or a lack of interest in things instead, and they may be less willing to talk about their feelings than younger adults. In some cultures, NIA adds, depression shows up mainly as physical complaints such as aches, headaches, cramps, or digestive trouble.

These are some of the signs NIA lists that are easy to explain away.

Losing interest in things you used to enjoy. Skipping the weekly card game, letting the garden go, or no longer caring about visits can be a sign, not a phase.

Running low on energy. NIA lists decreased energy and fatigue.

Moving or talking more slowly. NIA includes this physical slowing on its list, and it can be easier for others to see than for the person to feel.

Trouble concentrating or remembering. NIA lists difficulty concentrating, remembering, or making decisions. These changes are often mistaken for normal forgetfulness, or feared as the start of dementia.

Sleep that’s off. Trouble sleeping, waking up too early in the morning, or oversleeping can all be part of depression.

Eating more or less than usual. NIA says this usually comes with weight gain or loss that wasn’t intended.

Irritability or restlessness. Being short-tempered or unable to sit still can replace the sad mood people expect.

Drinking more. NIA lists increased use of alcohol or drugs as a symptom.

NIA’s rule of thumb is simple. If you have several of these signs and they last more than two weeks, talk with your doctor. They could point to depression or another health condition, and a doctor can sort out which. NIA notes that certain medicines and medical problems can cause symptoms of depression, which a physical exam and lab tests can help rule out.

Some things raise the odds. NIA lists medical conditions such as stroke or cancer, a personal or family history of depression, caregiver stress, sleep problems, loneliness and social isolation, lack of physical activity, and limits on everyday activities.

The link with memory is worth knowing. NIA says depression is common in people with Alzheimer’s disease and related dementias, that dementia can cause some of the same symptoms, and that depression can be an early warning sign of possible dementia. That is one more reason to bring changes to a doctor rather than guessing.

If you have Medicare, the first step costs nothing in many cases. Medicare Part B covers a depression screening once a year in a primary care setting, such as your doctor’s office, and you pay nothing if your provider accepts assignment. Follow-up treatment may carry a copayment or coinsurance.

Treatment works for most people. NIA says depression, even severe depression, can be treated, and that talk therapy and medication are common options. Families can help by encouraging a visit, offering a ride, or simply asking how someone is doing.
